`
`ABSTRACT
`
`Techniques for portable devices functioning as an electronic
`purse (e-purse) are disclosed. According to one aspect of the
`invention, a mechanism is provided to enable a portable
`device to conduct transactions over an open network with a
`payment server without compromising security. In one
`embodiment, a device is loaded with an e-purse manager.
`The e-purse manager is configured to manage various trans(cid:173)
`actions and functions as a mechanism to access an em ul ator
`therein. The transactions may be conducted over a wired
`network or a wireless network. A three-tier security model is
`contemplated to support the security of the transactions from
`thee-purse. The three-tier security model includes a physical
`security, an e-purse security and a card manager security,
`concentrically encapsulating one with another. Security keys
`(either symmetric or asymmetric) are personalized within
`th e three-tier security model.

`ABSTRACT
`(57)
`Techniques for funding an electronic purse ( e-purse) are
`disclosed. According to one aspect of the invention, a
`mechanism is provided to enable a portable device to
`conduct transactions over an open network with a payment
`server without compromising security. In one embodiment,
`a device is loaded with an e-purse manager. The e-purse
`manager is configured to manage various transactions and
`functions as a mechanism to access an e-purse therein. The
`e-purse is funded by interactions among the e-purse man(cid:173)
`ager, a payment server and a financial institution (its server)
`that maintains an account therefor.
